摘要

An approach incorporating the input-output feedback linearization and the sliding mode control is presented in this paper for the simultaneous multiaxis reorientation of a rigid spacecraft with flexible structures. Modeling of the dynamic system gives a set of coupled ordinary and partial differential equations, which describe the attitude dynamics of the spacecraft and the motions of the flexible structures, respectively. To apply the proposed attitude control law, the set of nonlinear equations governing the attitude motions were transformed into modified Rodrigues parameters(MRP) representation. Deformations of the flexible structures are assumed small under the control efforts and the governing equations are simplified by applying the mode-shape functions. The attitude feedback gain considering structure stabilization and system uncertainties is further determined by the use of Lyapunov function which ensures the control system to be stable and robust. Major advantage of the method is that only three attitude torque actuators in the hub are required for the proposed control law. Attitude detumbling to reorientation of a model spacecraft was tested and the simulation results were included.
